Abstract

L'invention porte sur un godet (38) comprenant une trappe de godet (86) et une mâchoire actionnée par choc (104) ayant une forme de « C » qui définit une lèvre (108) et un menton (112). La mâchoire (108) est montée rotative sur la trappe de godet (86) pour tourner entre une position de trappe ouverte et une position de trappe fermée et elle est positionnée de telle sorte que, lorsque la mâchoire (104) est dans la position de trappe ouverte, le menton (112) de la mâchoire peut être heurté par le corps (62) du godet lorsque la trappe (86) pivote pour prendre la position de trappe fermée. Le godet (38) comprend aussi un mécanisme de maintien ouvert pour maintenir le loquet de trappe dans la position d'ouverture du loquet de façon détachable lorsque le loquet est dans la position ouverte, et un mécanisme de verrouillage pour verrouiller le loquet de façon détachable lorsque le loquet est dans la position de trappe fermée. Le mécanisme de verrouillage comprend une barre (164) reliée à pivotement à la trappe (86) et une autre barre reliée à pivotement à la première barre (86) et au loquet et s'étendant entre la barre et le loquet.
